Research On The Theories And Methods Of Life Cycle Environmental And Economic Assessment On Electro-Mechanical Products

With the worse environment pollution, the government and people of the world became to be more and more conscious about the environment protection, besides this, the green trade tariff protection begin to show up between the countries, all of these have led to the coming-forth of the green product, and now these new type products gradually take the place of the traditional products. So the relative research about the green product become one of the concerning focus of the government, enterprise and academia. In this dissertation, the electro-mechanical products are selected as the main research object, based on the consideration of integration of the environment performance assessment and the economic performance assessment, a research about the theories and methods of environmental and economic assessment is proceeded, the main content is as follow:1. According to the analyses of the practical investigation, based on the summarization on the concept and meaning of the green products of the previous and combining the new concrete demand on the green products, a new comprehensive meaning about the green product is provided. And then a new concept about the green product design and a set of relative design principles is set and explained.2. According to ISO14000 series standards and the characters of the green electro-mechanical products, based on the life cycle assessment method, a new environmental and economic performance assessment system is put forth, and the key process of the system are analyzed and adjusted.3. Through the cost-profit calculation of the traditional products and the combination of the environmental and economical performance of green products, a set of mathematical model is built, that is suit to the environmental and economical performance assessment of the life cycle of the green product. Besides this, according to the practical situation, the assessment of green products is simplified, and through the simplification, the application of the assessment can be promoted. 4. During the environment and economic performance assessment process, the local influence factor has been taken into consideration. And the concrete influencethat the local influence factor makes on the environment and economic performance is discussed and researched in detail. Based on these, the deal method would be analyzed.5. Through the combination of the assessment technique of green product and the net technique, a set of net software about the environment and economic assessment has been programmed. It takes advantage of the network, a high speed developing information tool, to practice the assessment system of green product and make it more practical and accelerate the development and application of it.
